... 2) Looks like a standard normal density, only more spread out. 3) The spread of the distribution is indexed to a parameter called the degrees of freedom (df). 4) As the degrees of freedom increase, the t-distribution gets closer to the standard normal distribution. (Safe to use z instead of t when n ...
